The earliest Monument of the Eponymous Heroes attested by physical evidence may be dated to ca. 330. At this time it constituted a long limestone statue base which carried ten bronze statues—one of each of the heroes, and tripods at each end (probably in commemoration of the fact that the Delphic oracle was consulted for the choice of the heroes). The entire base was surrounded by a barrier of fence posts (some marble and limestone posts remain), with wooden railings. This monument served as a public notice board for tribal affairs, general notices for the Assembly, and the heroes may also have received worship there.
